    This article proposes a new plastification mechanism to model bentonite free swelling processes by using an elastoplastic approach. The formulation is based on an interaction function that defines the plastic macrostructural ...
  • Yustres Real, Angel; Jenni, Andreas; Asensio, Laura; Pintado, Xavier; Koskinen, Kari T.; Navarro Gamir, Vicente; Wersin, Paul (Elsevier, 2017-06)
    This study compares the capabilities of two numerical models that simulate the behaviour of compacted saturated MX-80 bentonite exposed to different chemical environments. Both codes have different approaches: one of them ...
  • Navarro Gamir, Vicente; Asensio, Laura; Morena Borja, Gema de la; Pintado, Xavier; Yustres Real, Ángel (2015)
    The current research proposes a method for obtaining the intra-aggregate (microstructural) and inter-aggregate (macrostructural) water content of MX-80 bentonite using data from water retention curves. Data associated with ...

    Using multiphysics computer codes has become a useful tool to solve systems of partial differential equations. However, these codes do not always allow for the free introduction of implicitly defined state functions when ...

    An approach is proposed for simulating the coupled processes of swelling and mechanical erosion of compacted MX-80 bentonites. The loss of mass at the water?soil interface is described by means of a simplified erosion ...
  • Alonso Aperte, Juan; Pintado, Xavier; Navarro Gamir, Vicente; Asensio, Laura; Yustres Real, Ángel (2013)
    A constitutive model of the volumetric behaviour of bentonite aggregates is proposed. The model is based on a state function to define the inter-aggregate (microstructural) void ratio and on a mass transfer function to ...
